Then, under the action of the two auxiliary fixing components 5, the insulation block is fixed. Then, close the box door 2, and then start the heating device 6 to make the heating device 6 convey hot air upward through the conveying pipe. At this time, under the action of the upper cylinder of the temperature measuring device 3, the temperature probe of the lower part of the temperature measuring device 3 is moved down to the upper surface of the insulation block, so as to carry out the thermal insulation experiment.

[0033] like Figure 4As shown, the auxiliary fixing assembly 5 includes two fixing plates 51, the lower surfaces of the two fixing plates 51 are fixedly connected to the front and rear parts of the upper surface of the insulation plate 4, respectively, the opposite surfaces of the two fixing plates 51 are overlapped with the front and rear sides of the rubber sealing gasket 41, the opposite sides of the inner walls of the two fixing plates 51 are fixedly connected with a hydraulic rod 1 52, the output ends of the two hydraulic rods 1 52 are fixedly connected with a connecting block 53, the opposite surfaces of the two connecting blocks 53 are fixedly connected with two symmetrical limiting assemblies 54, and the two limiting assemblies 54 are respectively located on the left and right sides of the filter screen 42, the outer walls of the front and rear parts of the two limiting assemblies 54 are respectively slidably connected to the inner walls of the two fixing plates 51, the opposite surfaces of the middle parts of the two limiting assemblies 54 are fixedly connected with fixed sealing assemblies 55, and the two fixed sealing assemblies 55 are located above the rubber sealing gasket 41;

[0034] Through the action of the two hydraulic rods 52, the two connecting blocks 53 can drive the two limit assemblies 54 to move in opposite directions, thereby limiting and fixing the insulation block on the upper surface of the rubber sealing pad 41. Then, under the action of the two fixed sealing assemblies 55, the insulation block can fit tightly with the rubber sealing pad 41 on the lower surface, thereby ensuring that the insulation block and the insulation board 4 are sealed by the rubber sealing pad 41, so that the heating equipment 6 will not affect the space on the upper part of the insulation board 4 when transporting hot air upward, thereby improving the accuracy of temperature measurement by the temperature measuring device 3.

At the same time, through the action of the moving wheel 543, the moving block 541 and the U-shaped plate 544 can be moved and adjusted more easily under the action of the hydraulic rod 1 52, thereby ensuring that they can move stably between the two fixed plates 51 under the drive of the hydraulic rod 1 52, thereby preventing dislocation.

[0037] like Figure 6As shown, the fixed sealing assembly 55 includes a fixed block 551. The side of the fixed block 551 close to the filter screen 42 is fixedly connected to the side of the U-shaped plate 544 away from the filter screen 42.

The outer wall of the middle part of the U-shaped plate 544 is clamped with a rubber protective plate 545.

[0040] Due to the function of the rubber protective plate 545, the movable block 541 will not cause damage to the surface of the thermal insulation block when restricting and fixing the thermal insulation block, thereby playing a protective role.

[0041] like Figure 8 As shown, the inner walls of the front and rear portions of the U-shaped plate 544 are fixedly connected to threaded rods 546, the outer walls of the upper and lower portions of the two threaded rods 546 are threadedly connected to rotating rods 547, and the opposite sides of the four rotating rods 547 are rotatably connected to clamping blocks 548.

After the four blocks 548 are moved out in turn, the rubber protective plate 545 can be removed from the outer wall of the U-shaped plate 544, and then the new rubber protective plate 545 can be re-attached to the outer wall of the U-shaped plate 544, and then the rotating rod 547 is rotated in the opposite direction in turn to make the four blocks 548 re-attached to the inner wall of the rubber protective plate 545, so that the rubber protective plate 545 can be easily installed, fixed, disassembled and replaced during use.

[0043] The working principle of the present invention is as follows: first, the box door 2 is opened, and then the heat-insulating block is placed on the central part of the upper surface of the rubber sealing pad 41, so that the heat-insulating block is located directly above the upper conveying pipe of the heating device 6, and then the two connecting blocks 53 are driven by the action of the two hydraulic rods 1 52 to move the two U-shaped plates 544 toward each other, wherein under the action of the sliding rod 542 and the moving wheel 543, the U-shaped plate 544 and the moving block 541 are able to move stably between the two fixed plates 51, and the heat-insulating block is fixed by the action of the two U-shaped plates 544, and then the U-shaped limiting frame 553 is driven by the action of the hydraulic rod 2 552 to drive the two L-shaped connecting rods 554 to move downward, thereby pressing and fixing the heat-insulating block, and at this time, under the action of the rubber sealing pad 41 on the lower surface of the heat-insulating block, the heat-insulating block can be sealed with the insulation board 4, thereby ensuring that the hot air delivered by the heating device 6 will not affect The temperature above the insulation board 4 is measured, and then the box door 2 is closed, and then the heating device 6 is started, so that the heating device 6 transports hot air upward through the conveying pipe. At this time, under the action of the cylinder in the upper part of the temperature measuring device 3, the temperature probe in the lower part of the temperature measuring device 3 is moved down to the upper surface of the insulation block, so as to carry out the insulation test. After long-term use, the rotating rod 547 can be rotated so that the rotating rod 547 can be moved under the action of the threaded rod 546, thereby driving the block 548 to move out from the inner wall of the rubber protective plate 545. After the four blocks 548 are moved out in turn, the rubber protective plate 545 can be removed from the outer wall of the U-shaped plate 544, and then the new rubber protective plate 545 can be re-clamped to the outer wall of the U-shaped plate 544, and then the rotating rod 547 is rotated in the opposite direction in turn so that the four blocks 548 are re-clamped to the inner wall of the rubber protective plate 545, so that the rubber protective plate 545 is easy to disassemble and replace during use.
